The variation of refractive index of a crown glass thin prism with wavelength of the incident light is shown. Which of the following graphs is the correct one, if D m is the angle of minimum deviation ?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
δ = A ( μ – 1) for thin prism, then more is the refractive index, more will be the deviation.
